摘要： A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.

摘要： A system is provided for monitoring a relative displacement of a pair of end-winding components. The system includes a structure mounted to the end-winding components at an angle with respect to the end-winding components for monitoring the relative displacement. The system further includes an optical fiber with a first portion including a fiber Bragg grating mounted to a surface of the structure to experience a strain resulting from a strain of the structure due to the relative displacement. The optical fiber includes a second portion internally routed through in the structure to the first portion mounted to the surface. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the end-winding components.

摘要： The present application provides a fiber optic sensor system. The fiber optic sensor system may include a small diameter bellows, a large diameter bellows, and a fiber optic pressure sensor attached to the small diameter bellows. Contraction of the large diameter bellows under an applied pressure may cause the small diameter bellows to expand such that the fiber optic pressure sensor may measure the applied pressure.

摘要： A system is provided for monitoring a relative displacement of a pair of end-winding components. The system includes a structure mounted to the end-winding components. The system further includes a fiber Bragg grating mounted to a non-curved surface of the structure, where the fiber Bragg grating is configured to reflect incident radiation having a peak intensity at a respective wavelength based on a strain of the fiber Bragg grating. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the pair of end-winding components.
